Can you install an asphalt driveway yourself?
Making your own asphalt driveway is hard work, and not a job for one person. If you have friends who will help you, it is possible to save a lot of money by doing your own driveway, even after the cost of rental equipment is factored in.
Is 2 inches of asphalt enough for a driveway?

Should I hose down my new asphalt driveway?
Even when fully cured, asphalt pavement can sometimes soften in extreme heat, or harden faster as temperatures drop. To temporarily harden the pavement, you can water down the surface with a garden hose. If soapsuds appear, don’t be worried. This is a reaction between the chlorine in the water and the asphalt.
Is asphalt better than concrete?
Concrete is more durable than asphalt. Because it is a less flexible material, it cracks in freezing temperatures, and many people turn to concrete patching products. Though it is more durable overall, when damages do occur, concrete repair is harder and costlier than asphalt repair.
Is blacktop the same as asphalt?
The materials that are used to make blacktop and asphalt are the same. Both are made from two ingredients: bitumen and crushed stone. The difference lies in how those ingredients are combined to make the final product.
How do you prepare the ground for an asphalt driveway?
The Complete 7-Step Process for Asphalt Pavement Installation Step 1: Demolition and Removal. Step 2: Grading and Sloping. Step 3: Prepare the Sub Base. Step 4: Proof Roll, Undercutting and Sub Base Repair. Step 5: Binder and Surface Course. Step 6: Install New Asphalt Surface. Step 7: Butt Joints and Transitions.
How hot does it have to be to lay asphalt?
During initial application, the asphalt should still be at least 220 to 290-degrees Fahrenheit. If the asphalt dips below approximately 185-degrees Fahrenheit before compaction is complete, its consistency stiffens up too much to finish the job properly.
How many inches should a blacktop driveway be?
A full-depth asphalt driveway is one that is made entirely of asphalt. The asphalt paving mixture is used from the soil subgrade to the top layer. For most cases, this top layer of asphalt of four inches or more is considered “adequate,” while 5-6 inches results in a driveway that is stronger and more stable.
Can you pour asphalt over grass?
You should never apply asphalt directly over grass. Doing so ensures your asphalt surface will be destroyed in record time. Soil should always be scraped and excavated to allow for the installation of a proper base.
Does asphalt need a gravel base?
Strong blacktop driveways are typically built using crushed angular gravel as a base. This gravel needs to be a minimum of 6 inches thick for light vehicle traffic such as cars and pickup trucks. The 2-inch-thick layer of blacktop should be fine as long as the gravel base is installed correctly.
What is the minimum thickness of asphalt?
Asphalt Thickness: Asphalt driveways need to be a minimum of 2” thick and are typically 3” (compacted).
How do I turn my gravel driveway into asphalt?
An inexpensive method for paving a driveway consists of gravel or crushed rock over a graded, packed dirt bed. If you already have a gravel driveway and want to pave over it, the least expensive option is adding a hot-asphalt seal-coat layer over the surface of the gravel, followed by a layer of crushed rock.
Can you put asphalt over rock?
In short, yes, you can blacktop over gravel. To convert a gravel driveway to asphalt, there are a few steps that need to be followed, but the project can be completed relatively easily.

Look carefully at your driveway after a rain. Fill potholes and other low spots. Most gravel driveways develop low spots over time. Compact the gravel.
Should I spray my new asphalt driveway with water?

Why do they put sand on new asphalt?
Asphalt cement is the binder, or glue, that holds together the sand and stones that make up a blacktop drive, road or parking lot. The stones and sand in blacktop are immune to UV damage from the sun.
Is it OK to rain on new asphalt?
In general, asphalt cannot be installed when it is raining. When rain comes into contact with fresh asphalt, it causes the oil to rise to the surface which can affect the curing time and the finished product. If asphalt is paved while it’s raining, it can reduce the overall quality of the asphalt.
